钢纤维混凝土配合比设计进行的步骤是:(1)根据强度标准值或设计值以及施工配制强度提高系数,确定试配抗压强度与抗拉强度或试配抗压强度与抗折强度。(2)根据试配抗压强度计算水灰比。(3)根据试配抗拉强度或抗折强度,按规定计算或通过已有资科确定钢纤维体积率。(4)根据施工要求的稠度通过试验或已有资料确定单位体积用水量,如掺用外加剂时应考虑
Steel fiber concrete mix design steps are: (1) According to the strength of the standard value or design value and the construction of the preparation of the strength to improve the coefficient to determine the test with the compressive strength and tensile strength or test compressive strength and flexural strength. (2) calculate the water-cement ratio according to the test compressive strength. (3) According to the test tensile strength or flexural strength, calculated according to the regulations or through the existing resources to determine the steel fiber volume fraction. (4) According to the consistency of the construction requirements, the volume of water used per unit volume should be determined through the test or the existing data, and should be considered when admixture is added
